Modular Indirect-Fired Bent Tube Heater

Providing clean and tempered makeup air to meet your application needs. The push-through design ensures that combustion fumes will
not enter the fresh air stream.

Additional Features

The Modular Indirect Fired Bent Tube Heater is designed to deliver clean air into an indoor environment. Units are designed for indoor or outdoor installation, and can use either Natural or
LP gas. the standard unit includes a blower module and the IBT heater module that is approved in the United States and Canada. the unit is listed to the ANSI Z83.8-2006 and CSA 2.6-2006 standards.
Each furnace has a 6:1 Turndown Ratio and a maximum Turndown of 28:1 for the entire unit, depending on total required BTU Capacity and number of furnaces in the unit.

Every unit is programmed to start in high fire mode to ensure consistent light-off and is equipped
with an electronic, Vernier-type fully-modulating control system. The duct furnaces are all type-409 stainless steel,
and certified by the American Gas Association and approved by the Canadian Gas Association. Each model utilizes at
least one, but not more than two, modulating stage(s) and between zero and two additional ON/OFF stages depending
on the required heat output. In addition, the speed of its power-vent blower on the modulating furnace(s) is varied
as the gas flow changes; thereby maintaining a constant 80% combustion efficiency over the entire gas-firing range
of the unit.

Combination packages that include both exhaust and supply fans mounted on a single roof curb are also available; please contact your sales representative for more information.
